Discussion FAMILY A It has already been shown that Huntington's chorea is not uncommon in the Moray Firth area but that it is confined to those connected with a fishing community. The ancestry of the two patients described here has been traced back about 100 years without finding any relatives with chorea. There has been no association II with the fishing families, and any connexion is most unlikely in earlier times because of the almost com-
